These files are best played on smaller, dated devices
Definition and fidelity are sacrificed in favor of storage space and portability
for the HEVC(x265) 360p files were tested on a 1.6Ghz x86 laptop using MPlayer
405p files were tested on a 1Ghz Dual Core ARMv7 Android device using the MX player app
Devices lesser than these and the files probably won't play.
Better devices and up-to-date apps should play them okay
